Hello, all: I've played around a lot with building little games for PC, but I've never built an app for a phone. I understand that the most popular resolution is 1920 by 1080, but I want my app to be vertical. So, do I set the room resolution for 1080 x 1920? Also, my graphics are smaller than this resolution. About half the size, actually. Basically, I'm asking how to set up. Once I know the best room size, I'll be good to go. But any other tips would be helpful. Thank you.
